' LUBRICATOR FOR CAR-WHEELS.-

Specification of Letters Patent.

Application filed January 7, 1911. Serial No. 601,410.

Tov all 'whoin it may concern:

Be it known that I, CARL F. GEllLIN-Glllt, a citizen of the United States, residing in Oregon, have invented certain new and useful Improvements in Lubricators for Car- \V heels, of which the following is a specification.

"My invention relates to that class of lubricators for car wheels in which provision is made for applying oil, grease, or other suitable lubricant to the flangesof the wheels.

It is well known that where the flanges of car wheels are properly lubricated the wheels are prevented from leaving the track when rounding short curves, and the object of my invention is to provide an improved lubricator for this purpose.

In the accompanying drawings, Figure 1 shows a bottom plan view partly in section of a lubricator embodying my improvements. Fig. 2 shows a section thereof on the line Q2 of Fig. 1. Fig. 3 shows a horizontal section of the lub ricator. Fig. 4 is a detail View in section showing the manner of adjustably connecting the 'lubricator with its support. Fig. 5 line of Fig.- 1.

The reservoir A for the oil, grease, or

shows a section on the other lubricant, is provided with an a'rm a, connected with a rod B that extends into a tubular support C that may be connected 'with the car truck.

able in the tube C but its movement is limited by means of a bolt 1) which extends through the rod B and through slots 0 formed in the tube C. A flange a is formed integrally with the arm a and the reservoir A and isadapted to extend over the flange of the wheel X as indicated in Fig." 2. By adjusting the rod B .in the tube C the flange a may be moved toward and from the flange ot the car wheel. The reservoir A may be filled through a lubricant receiver D closed by a screwlug d. Within the reservoir A is ajp'istonattached to a rod F that extends through a screw-plug G that engages a threaded'opening in the boss 7:. formed on the. reservoir A. The screw-plug G is formed witha squared and g to which a suitable tool may be applied to turn it and thus move it inward or outward relatively to the interior of the reservoir. A spring The rod B is adjust-.-

H is interposed between the piston E and the inner end of the plug G and tends to move the piston toward the delivery opening e thereof. A lock not I is carried by .the scrcw plug and prevents the latter from turning when once adjustedto the proper position. The outer end of the rod F is threaded, as shown, and carries a. nut J and this rod is provided at'its outei' 'e iid' with a handle. K. When the nut J is in the position shown in Figs. 1 and 3, bearing upon the end of the plug G, inward movement of the piston E is prevented, but when the nut J is moved toward the handle K a further inward movement of the piston E is permitted and this movement will be efi'ected by the spring II. By adjusting the nut J properly on the threaded portion of the rod F the inward movement of the piston E may be regulated with greatnicety.

flange of the wheel X, as indicated in Fig. 2. The rod is adapted to move back and forth through the opening 0 and its inner portion enters a hollow screw-plug N. A spring 0 within the screw-plug bears upon the inner end of the-rod M and presses'it toward the flange of the wheel X. The inner end of the plug N is shaped to form a valve "for opening and closing the exit port e and this plug is threaded, as shown, and engages corresponding threads in a boss 0 formed on the reservoir. By means of a handle P on the plug the opening atthe. exit ort 6 may be opened or closed" and regulated. A lock-nut Q. serves to hold "the plug firmly in place when once adjusted. I

By the devices shown and described, the

.feed' of the lubricant may be very nicely regulatedand the flanges of the wheels may be kept lubricated without waste of the lubricant.

I claim as my invention:

1. A car wheel lubricator, comprising a reservoir :for the lubricator, a flange con-' nected therewith and adapted to engage the flange of'the car wheel, an arm connected with the reservoir, means for adjustably connecting this arm with a su port, a valve for regulating the flow of lubricant from the reservoir, :1. rod connected with thevalve and adapted to press against theflange of screw plug adjustable in the Wall of the res:

ervoir into which the grooved rod projects and a spring within the plug pressing against the inner end of said rod.

3. A. car wheel lubricator, comprising a reservoir having an exit opening, a grooved rod moving in said exit opening, a hollowscrew plug adjustable in the wall of said reservoir into which .the rod projects, a spring within the plug pressing against the inner endcof said rod, and a spring-pressed piston for forcing the lubricant toward the plug in a direction transverse to that in which said plug and the grooved rod move.

4. A car-wheel lubricator,. comprising a reservoir having an exit opening, a grooved rod extending through this o'pening, a hollow screw-plug into which the rod projects, a spring within the plugbearing against the rod, and a valve on the inner end ofv the plug for opening and closing the exit opening.

In testimony whereof, I have hereunto subscribed my name. h
